No piston required to feel the difference. I put the stage 1 in my 06 650l and from mid rpm to redline that sucker pulls hard, used to pull hard in the low rpms only to midrange, after the cam I changed the gear ratio to 14/48 to get the low end grunt back. Thing is really scary will easily pull 2nd gear wheelies and maybe 3rd but I'm too scared to try it:cry: Not that good of a rider to be holding 40mph+ on one wheel. Did all the other stuff 1st,Daves mods 165main/58 pilot/uni filter/Supertrapp IDS2 with 19 discs/Drilled the air box/ de-snorked.It was the most noticeable mod, even better than the re-jetting. Oh yeah pulled the smog stuff too but kept it just in case California starts smogging the bikes:mad:
